It was shown that 2,4,5,2',4',5'-hexachlorobiphenyl (6-CB) administered to adult female mice accumulated in their nursing offspring more rapidly than a dose administered to weanling mice when treated animals were bred at equivalent ages. This suggested that the PCB was eliminated from the maternal animal relative to its time of sequestration into storage(More)
2,4,5,2',4',5'-Hexachlorobiphenyl (6-CB) is mobilized from rodent tissues during the lipid depletion associated with food restriction or lactation, the latter condition resulting in the substantial elimination of the maternal body burden of the chemical to nursing offspring. The present study was undertaken to determine whether the rate and/or magnitude of(More)
We have numerically modelled the thermal effects of yellow (577 or 578 nm) light illumination on the ectatic blood vessels of port wine stains. We investigated the effect of the laser treatment parameters of light irradiance and illumination time on the extent of coagulation (coagulation thickness) of the endothelial cells of the ectatic vessels. We assumed(More)
A questionnaire was sent to 242 patients who had undergone treatment with yellow light (578 nm) from a copper vapour laser for a port wine stain (PWS), for facial telangiectasia (FT), or for a spider naevus (SN). The questionnaire covered the social implications of the lesion, the physical appearance of the lesion after treatment and the patient's judgement(More)
Thermal profiles of ectatic capillaries, modelled on those found in port wine stain birthmarks, are calculated by a method of finite differences. Yellow 578nm light is assumed to illuminate these vessels. The coagulation of endothelial cells is assumed to occur when the cells are heated to at least 70 degrees C. We model this by asking that a point 6(More)
Market coordination of transmission loading relief in an electric grid with multiple regions implies trading across boundaries. Starting with the early framework for transmission loading relief that relies primarily on administrative priorities, introduction of prices and explicit trading to redispatch across regions would provide market solutions for(More)
AGA3 also had a very short half-life in humans (8). Chemical modification of free amino groups can increase the plasma half-life of some asparaginase and glutaminase-aspa raginase enzymes in animals (12, 20). In previous studies, we have shown that treatment of AGA with succinic anhydnide produces a uniform preparation with the same catalytic activity and(More)
Epididymal adipocytes, isolated from rats pretreated with [14C]-2,4,5,2',4',5'-hexachlorobiphenyl (6-CB), were utilized to examine the relationship between the mobilization of lipid and 6-CB and to determine whether 6-CB was differentially associated with subcellular organelles over time as has been demonstrated for newly synthesized lipid. Lipolysis,(More)
